P10-03 Developing online health community platform for enhancing physical activity in the community

Abstract Virtual communities are emerging in many aspects of health activities and widespread in health management. Online health communities offer a virtual system where people with common interest, specific health needs can exchange information and experiences with other people with the same condition as well as getting support from peer and professionals. The objective of this study is to develop an ICT platform enhancing community resident participation involving in the chronic disease prevention and physical activities. The aim of this platform is to promote physical activity of community residents for health promotion and disease prevention goal attainment. Health promotion goals for enhancing physical activity were set by health care professionals based on scientific evidence. Instead of individual plan to set the goal by themselves, the platform offered them tailored goal with their conditions and then suggested them to participate in group shared their physical activity goals. The platform encouraged the active participation of community residents though adherence physical activity of health communities in which they were members.The ICT platform provides a place where community residents with chronic conditions or even healthy people who want to promote their health be able to find an appropriate group for together prevent disease and enhancing physical activity. The platform in the study allowed community residents to develop their own communities and invite other members to participate with them. This online community intended to empower community residents to increase their involvement in their self-management and pushing the active participation in phycial activities. Function such as reminder of activity participating was added. Future study will be conducted to evaluate changes in health promotion self-efficacy, health goal fulfillment, health-related quality of life, and shared decision-making after using the Health Community Platform among community residents. Extensive research initiatives are needed to determine the impact of virtual health communities on patient outcome, the overall process as well as quality and access of care.


Issue/problem
Physical activity (PA) can prevent falls, a leading cause of death globally. Alternative delivery channels may increase the ''reach'' of interventions into older adult populations in areas which lack trained instructors. Using technology is one alternative to traditional, face-to-face group classes where instructors and participants are in the same room. We delivered a PA program via the Internet for older adults in rural West Virginia (USA). This alternative could help other countries reach more older adults and reduce falls. Description of the problem Tai Ji Quan: Moving for Better Balance Õ (TJQMBB) is an evidence-based intervention for older adults that reduces falls.
Adults, ! 55 years, attended free, 1-hour tele-TJQMBB sessions, twice weekly, for 16 weeks at 5 remote community sites (3 urban, 2 rural). Trained instructors (new to TJQMBB) led 6 classes from a classroom for participants at remote sites. Instructors/sites used minicomputer, web camera, microphone, and television(s) for live, 2-way verbal/audio exchange. A CPR-certified person was present with participants. This project identified barriers to implementing tele-TJQMBB. Data on barriers were collected from instructors' class logs and summarized.

Results
Fifty-two adults (81% female, mean age 70) attended 23 (median) of 32 sessions. Barriers that caused session cancelations included: participant vacations/unavailability (n = 7), inclement weather (n = 4), technical issues (n = 2), no CPR person (n = 1), classroom not available (n = 1), site closed for state holiday (n = 1), competing event at site (n = 1), and ill instructor (n = 1). Technical barriers during sessions included interruptions/lack of audio, video freezing, and Wi-Fi/Internet connectivity problems. Two participants did not like videoconferencing. Lessons Tele-TJQMBB may be easier to teach with instructors who have already taught the program in-person. Selecting instructors/sites that are comfortable with technology may reduce technological barriers. Some older adults may still prefer faceto-face classes. Most cancelations were due to reasons normally encountered in face-to-face classes. Use of technology added new barriers that will need addressed for future classes.

Main messages
Technology reached older adults in areas with no instructors.

Background
Despite the crucial role of regular physical activity (PA) for preventing chronic non-communicable diseases, fewer than half of older adults in Germany engage in the recommended levels.
Objective: The aim of this study was to compare acceptance and effectiveness of two interventions for PA promotion among initially inactive community-dwelling adults aged 60 years and above in a nine-month randomized trial with a cross-over design. Methods Participants were recruited offline and randomized to (a) a print-based intervention (PRINT n = 113) and (b) a web-based intervention (WEB, n = 129). Thirty percent (n = 38) of those in group (b) received a PA tracker in addition to WEB (WEB+, (c)). All intervention groups were offered ten weekly face-toface group sessions led by trained student assistants. Afterwards, participants could choose to stay in their group or cross over to one of the other groups. Group sessions were continued monthly for another six months. Three-dimensional accelerometers to assess PA at baseline (T0), three-months (T1) and nine-months (T2) were employed. Intervention acceptance was assessed via self-administered paper-based questionnaires. Linear mixed models were used to calculate differences in moderate-to-vigorous PA (MVPA) between time points and intervention groups.

Conclusions
Despite high levels of acceptance of web-and print-based interventions for PA promotion and little movement between
